"A member of the Paris Geographical
Society suggests that instead of de-
posting provisions and other stores for
Arctic explorers in cairns or rocky
structures above ground, they ought to
be placed in subterranean stations ex-
excavated for the purpose. BY the

Gently acquired fine specimen of the
extinct musk OK of North America.
The bones, which are remarkably well
preserved, were unearthed near the
Missouri river at Council Bluffs in the
formation known to biologists as the
loess. This creature, like the modern
musk OK, is supposed to have been
clothed with q long fleece, and the dis
covery of the remains at Council Bluffs
indicates that low temperature must
have prevailed in that region during the
period when the loess was accumulat-
ing, so that Arctic animals have found
the climate comfortable there--M Y.

Paper window-glass is now said to
be an assured fact. As described: "a
window-pane is made of white paper,
manufactured from cotton or linen,
and modified by chemical action.
Afterward the paper is dipped in q
preparation of camphor and alcohol,
which makes it like parchment. From
this point it can be nodded and cut
into remarkably tough sheets entirely
transparent, and it can be dyed with
almost the whole of the aniline colors,
the result being transparent sheet,
showing far more vivid hues than the
best glass exhibits. Public Opinion.
